To all whom imag concern:

Be it known that I, lViLLIAM A LWVEM/'Emf a citizen ofthe United States, residingrin they city and county of Philadelphia, State of Pennsylvania,.have invented a newy and useiul Bed Bottom foi'-Hosp1tal Bedsteads, f

of which thelfollowi'ng is a specification.'

My invention consists of a bedstead pro-` vided with a bed bottom more particularlyl designed for hospital purposes, the same belng formed of sections which may be adusted 1n height and angularlyaccording to requirements of examination andy treatmentl of patients, the means employedy and the operation thereof being lhereinafter set forth.'v

The invention is ,satisfactorily,illustrated in the accompanying drawing,.butthe important instrumentalities `thereof may` 'be varied, and so it is tobe understoodv thatthe Figure 2 represents a vperspective view thereof showing the bedbottom in different` i position from that 'shown in .Figure 1.

Figure 3 represents a side elevation of members at the foot vend of the bedstead det-ached therefrom. w

Figure 4 represents a perspective view of members on an'enlarged scale at thehead end of the bedstead detached therefrom- Figure represents a topplan view of members on the frame of the bedst-ead for operating the bed bottom, the latterV having been removed.

VFigure `6 represents members shown in Figure 5. l v c Figure 7 lrepresent-sia longitudinal section of certain members on an enlargedscale adapted Vto operate the vbed bottom detached in part from the'bedstead( v Figure 8 represents a longitudinal section on an enlarged scale'of adjacent jointed poi tions of the adjustablesections of the bedbottom, on the line 8- 8 Figure 5.

Similar numerals of reference .indicate corresponding parts in the figures.

1 designates the frame of' the bedstead composed ofthe head board 2, themfootboard 3, the side rails 4, the cross bar A5on the ends of the latter, and the brackets 6 which latter connect said lside rails and board.

asideelevation ofthe securedtheretoby the screw 26 v and which PATENT; OFI-ISC Swivelled on the bracket@ on the cross bar of'the footl end of thesiderails are the rotatable 4sleeves 7 and 8, one above'the otherV and'whichlare adapted to be opera-ted' by a `suitable cranlrhandle 9.

fitted' in itv the screw rod 12, the forward end of which iszconnectedwith the travelling coupling 13 to ywhose side arev pivotallylcon- In the sleeve is` the nut 10 which is sie-' cured thereto by the screw 11 iand which has nectedthe'arms 14 which diverge from' said traveller and have their outer ends pivotally connected with v the raising and lowering arms 15 ofthe bed bottom to lie-hereinafter described, the ends of,l said arms adjacent to the side rails being mounted on the cross rod lion'whose terminals are mounted the krollers .'17 "which VAare supported on thefrun-Av ways 1 -8, it'fbein'g ,noticed that Vthe latter arev securedZ to'lthe side,v railsiat'tlieffoot endof I saidfrai'nes being connected-bythe pivotal joints 23so that as the framel 20 Ais placed in different angularvpositions it may main thefbedsitead and'depend therefrom and that they are inclined andV ascend` from their tain the latter, vit now being noticed that the i armsl.v are pivotally connected with 'the frame of th'eifs'ection V21'y of salidbody section19. ,l f The'zframe of Lsaid ysection 2l "ha's its side memberspivotally `connected `with the brackets 24 which are connected theside `j InV the sleeve 8 is the.; which' has fitted in it'the screw rod 27, thefor-v ward end rof which passes freelyv through the collar 28`whichis carried by the traveller 13,said rodbeingA alsovsupported in and guided byfthe collar '29 which is, carried by the'cross rod 30, the latter having its ends secured tothe brackets24.

' v The'rod 27 isextended beyond the collar 29, the extension being pivotally connected with the divergent arms 31 whose inner terminals'are connected with the radial arms 32 of the head 'section SSofthe springbedv ways, it being notceq'that'the latterare r secured to the side rails at'the head end of the bedstead and depend therefrom and that they are inclined and ascend from their lett hand ends to the right hand ends, see F iguies 1 and 4.

It will be seen that when the body portion of the bed bottom is to be raised and adjusted in angular form, say as in Figure 2, the sleeve 7 is rotated and with it the nut 10. This pushes the screw rod 12, in the present case to the left, and with it the coupling 13, the divergent arms 14, and the arms 15 which are connected with the sides of the front frame 21 of the body section 19. This advances the cross rod 16 of said arms 15 and causes the rollers 17 to ascend the runways 18 and elevate the arms 15 and the body section 19 of the spring bed bottom placing the 'fra-,me 21 turning on its axis on the brackets 24 and so being placed in an inclined position elevated above the side rails of the frame of the bedstead. The trame 2O of said section 19 which has also been raised may be adjusted to a required angle from the sect-ion 21, it being capable of being raised or lowered at the joints 23 which owing to the rictional i nature thereot1 will retain said section 2O in the langular position to which it has been placed.

Itis evident that said section 19 may be adj usted in height by being moved to a greater or less extent by the operation of the sleeve 17 and that by the entire reverse rotation ot' the latter said section 19 may be'returned to normal vposit-ion placed flat on the bedstead in which case the rollers 17 descend the runways A18 and so by the intermediate mechanism draw down the frame of the section 19.

The head rest section 33 may also be raised and elevated by rotating the sleeve 8, whereby the screw rod 27 is pushed inthe present case to the right, thus operating vthe divergent armsBl and the arms 32, vthe latter being pivotally connected with the frame of said head rest section 33, said frame being mounted on the brackets 24, said arms 32 being also mounted on the rod 34 which is also moved by the divergent arms 31 and so the rollers 35 travel on the runways 36 and ascend the same, causing the elevation of the head rest section on its axis, it being evident also that said head rest section may be elevated to a greater or less extent by the extent of rotation of the sleeve 8, and the consequent motion of the screw-rod 27 and the mechanism intermediate of the latter and said head rest section, and that bythe entire reverse rotatin of said sleeve the rollers 35 descend the runways 36 and the section is drawn downrand placed in normal position flat` onthe bedstead.

The reeend of the frame 2O of the'body section 19 of the bed bottom is provided with friction rollers 37 which are adapted to travel on the side rails 4 and so ease the to and from motions of said section.

rlChe free end of the head rest section 33 is provided with depending legs 38 which when said section i's lowered, are adapted to rest on the side rails 4 and so support said section. Y

The pivotal joints 2S of the frames 2O and 21 of the body section 19 are con? structed as follows:-

in the adjacent ends ot said frame are connected the butts or leaves 39 which are provliifled with the knuckles 40 through which are passed the axial and securing pintle 41 forming together hinge like members which allow said frame to articulate and be placed angularly to each other as shown in Figure 2, but the inner sides of said butts are divergent or obliquely outward from the knuckles as at 42 so as to allow primarily spread apart spaces 43 between them. N ow as the trame 21 Iis raised it draws the frame 2O after it andelevates it and the oblique faces ot the butts on the frame 20, gradually closes on the oblique 'faces of the butts on the frame 21 and contacts therewith as rstops whereby the frame 2O is held elevated and inclined on the frame 21 as stated above in Figure 2, but'as Vthe iframe 21 may be raised or lowered to a greater or less extent the frame 20 may be placed at a desired'elevation and angularity in harmony with the frame 21 to form somewhat of a Y/-shaped figure as in Figure 2, for placing'the patient thereon for-treatment or an operation according to requirements, it being evident that the latter frame 21 sustains the former frame both in its elevated and angular adjustment and this may be varied by raising or lowering the trame 21 more or less according to the requirements of the body of the occupant on the section 19.

Thehead section 33 is yadjustable Iin height and angularity according to requirements for treatment or an operation as has been stated independent of the section 19.

Having thus described my invention what I claim as new and desire to secure by Letters Fatent, is
